USB Function Configuration on 40-Pin

On the ROCK 5C's 40-Pin interface, the following pins can be configured for USB 2.0:

• USB4_DM: Pin number 28, resistor location R104.
• USB4_DP: Pin number 27, resistor location R106.

By default, Pin-27 can be configured in software for functions such as GPIO0_C7 (see 40-Pin Pinout), while the USB4_DP signal is not activated on the hardware. Pin-28 can be configured in software for functions such as GPIO0_D0 (see 40-Pin Pinout), and the USB4_DM signal is also not activated on the hardware. To change these pins to USB functions, please follow the steps below to modify the reserved resistors:

• Remove the 0-ohm resistors at R169 and R170.
• Solder 0-ohm resistors at R104 and R106.
